> I know with electricity whether you do it per code or not a licensed electrician has to sign off before you can sell your house. at least i think that's how it is..
Where? No electrician is inspecting every house that goes up for sale in the US. Sure you can ask an electrician to inspect a house electrical… but that doesn’t bar a house sale anywhere I’ve ever seen.
For the home inspections I've been a "walkthrough witness" to, the "electrical inspection" portion involved the inspector opening the normal access door to the breaker panel levers, and plugging in one of those $5 Home Depot wiring fault detectors into a few random plugs here and there to verify no wiring faults appear.
But they do not remove the panel cover to look inside, nor do they open up any receptacle box anywhere to look at any of the wiring inside. So they wouldn't know (nor discover) if the wiring job was done well or done in a shoddy manner.
